Inmates rioted at the federal prison outside Talladega on Thursday night and fires erupted in the complex, knocking out power in part of the prison, authorities said.
There was no immediate word from prison officials on how many inmates might be involved or the extent or cause of the rebellion. Buses were being brought in to move many of the inmates to the county jail.
Six people reportedly were treated for injuries, including five prison workers and one firefighter. They suffered from cuts, bruises and smoke inhalation.
